Abelian varieties, modular forms and moduli

The aim of the meeting is to discuss recent developments, techniques and open questions in the area of abelian varieties and their moduli spaces, modular forms, number theory and combinatorics, automo...

On the Aleksandrov-Bakelman-Pucci estimate for weighted one-Laplacian

In this talk, I will present a new bound for solutions to the Poisson problem associated with the weighted one-Laplacian. The Aleksandrov–Bakelman–Pucci (ABP) estimate has long been a fundamental tool...

Small-time asymptotic behavior of the spectral heat content for isotropic Lévy processes

The spectral heat content (SHC) measures the total heat contained in a bounded domain at a given time when the initial temperature inside the domain is set to be one, and the temperature outside the d...

Minimal shapes on the hyperbolic lattices and the emergence of metastability

We investigate geometric and dynamical aspects of hyperbolic lattices arising from regular tilings with 1/p+1/q<1/2. We first characterize finite shapes with minimal perimeter and show that the rat...

Recent progress on multi-valued harmonic spinors

A little over a decade ago, Taubes and his disciples started to observe non-compactness phenomena in gauge theories in dimensions three and four that are linked with multi-valued harmonic spinors, 1–f...

La Matematica a Roma tra le due Guerre mondiali

La matematica a Roma raggiunge il suo massimo sviluppo nei primi anni '20 del Novecento, quando viene variamente definita La Princeton degli anni '20 (Lefschetz) e Il Paradiso della geometria (Zariski...

Exponential decay of correlations in hyperbolic supersymmetric nonlinear sigma models at high temperature

Supersymmetric nonlinear sigma models arise in the theory of disordered systems and share key features with O(N)-type models. They also exhibit surprising connections with probabilistic models such as...

The Weyl functional on connected sums of four-manifolds

The Weyl energy on four-manifolds is a geometric functional related to the Chern-Gauss-Bonnet formula. Similarly to Willmore’s functional for surfaces embedded in the three-dimensional Euclidean spa...

A non-Archimedean Calabi-Yau theorem

In Kähler geometry, the Calabi-Yau theorem establishes the existence and uniqueness of Kähler metrics with prescribed volume form. In this talk, I will present a non-Archimedean version of this theore...

La matematica a Roma dall'Unità d'Italia alla Prima Guerra Mondiale

La storia della matematica a Roma, dall'Unità di Italia sino al termine della Prima Guerra Mondiale, è strettamente legata alla vita politica, sociale e culturale del Paese. Le sue vicende restituis...

A quick introduction to motives

In this talk, I will give a gentle introduction to the theory of motives, as developed by Voevodsky. I will focus on the basic ideas and main properties, explaining how motives are related to algebrai...

Dispersive estimates for the Dirac-Coulomb model

The Dirac equation is one of the fundamental equations in relativistic quantum mechanics, widely used in a large number of applications from physics to quantum chemistry. From the dynamical point of v...
